Could a solar eclipse over Europe during the day affect the power generated by Germany's photovoltaic systems or solar panels, thereby challenging the reliability of the electrical supply across the country?

A new analysis based on simulations and data from the partial solar eclipse that occurred over Europe on the morning of March 20th indicates that such shadowing causes a sudden drop in the power gradient, followed by a steep rise. However, during the shadowing on March 20th, the amount of imported power rose and the amount of exported power fell accordingly.

Using solar or wind power to produce carbon-based fuels is a self-defeating approach to making a greener world, but when governments decide to engage in advocacy rather than science, and throw money at problems, bad corporate habits are learned. Instead of funding more basic research to make green energy viable, the White House opted to engage China in a price war on solar panels, and $72 billion later we have the same issues.

A new way to store methane could speed the development of cleaner-burning natural gas-powered cars that don't require the high pressures or cold temperatures of today's compressed or liquefied natural gas vehicles.

Natural gas is cleaner-burning than gasoline, and today there are more than 150,000 compressed natural gas (CNG) vehicles on the road in the U.S., most of them trucks and buses. But until manufacturers can find a way to pack more methane into a tank at lower pressures and temperatures, allowing for a greater driving range and less hassle at the pump, passenger cars are unlikely to adopt natural gas as a fuel.

Though activists want to retreat into the past and have less energy available for the public (which will impact the poor) a more progressive approach is to look to science and the future - but that will only work if there are stable policies in place.

Oddly, this progressive thinking is coming from energy corporations rather than environmentalists. A group of electricity corporations are creating a picture of a future high-tech energy mix that would help nations meet climate-related CO2 reduction pledges and the expanding demand for electricity.

Burning a candle could be all it takes to make an inexpensive but powerful electric car battery, according to new research published in Electrochimica Acta. The research reveals that candle soot could be used to power the kind of lithium ion battery used in plug-in hybrid electric cars.

The authors of the study, from the Indian Institute of Technology in Hyderabad, India, say their discovery opens up the possibilities to use carbon in more powerful batteries, driving down the costs of portable power.

In Australian homes, reliable hot water supplies for taking showers or bathing the kids are taken for granted. But this has a significant cost – conventional hot water heaters can account for up to 30% of household energy use and can be significant carbon emitters.

One alternative is solar hot water, which can supply more than 90% of household hot water and reduce energy bills by 50-85%, as well as lowering carbon emissions.

A few years ago, I couldn’t read an energy bill beyond the charge levied. I couldn’t tell you how energy was measured, or ultimately how its use related to making my life better or worse, let alone how it affected broader society and the planet.

I resolved to change this. I studied energy and sustainability at university, and have gone on to teach there. Throughout this time my wife and I have made many changes to how we use energy at home. Yet when we decided to take a closer look into our electricity bill, we were surprised by what we found.

In a radio interview , Prime Minister Tony Abbott raised what he described as the “potential health impacts” of wind farms.

If you are a hunter and accidentally shoot an endangered eagle, you could go to jail and you will certainly have a criminal record. If you are a wind turbine company, you kill 100 eagles a year and pay a token fine.  An estimated 75 to 110 golden eagles die at a wind-power generation operation in Altamont, California each year. That is about one eagle for every 8 megawatts of energy produced yet no one is in Federal prison. 

When government scientists determined that there would be negligible environmental impact due to the Keystone XL pipeline, another 400 miles of new, safer pipeline in an area where 20,000 miles of older pipeline already existed were not going to ruin the ecology, President Barack Obama ordered them to study it again.
